[0006] A hot water bag quality evaluation device includes a servo electric cylinder, a force value sensor, an upper pressing plate, a lower pressing plate, a profile frame, and a PLC control cabinet. The servo electric cylinder is vertically arranged on the profile frame; one end of the force value sensor is connected to the lead screw nut of the servo electric cylinder, and the other end is connected to the upper pressing plate; the lower pressing plate is arranged on the bottom plate of the profile frame and is located below the upper pressing plate; the PLC control cabinet is signal or electrically connected to the servo electric cylinder 1 and the force value sensor.

[0007] Further, the servo electric cylinder is a folding high-precision electric cylinder with a stroke of 300 mm.

[0008] Further, the force value sensor is a 5000N high-precision sensor with an accuracy of 0.01%.

[0009] Further, one side of the lower pressing plate is provided with a U-shaped groove.

[0010] Further, the profile frame is an aluminum profile frame, and anti-slip feet are provided at the four corners of its bottom plate.

[0011] Advantages of the Utility Model

[0012] The hot water bag quality assessment device provided by the utility model controls the stroke, speed, time, force value and number of tests of the upper pressing block through a servo electric cylinder, and only requires single-person operation to quickly conduct tests, with high efficiency, accurate data and good reproducibility.

[0013] By detecting the strength of the hot water bag, the utility model can identify product defects, thereby comprehensively evaluating the design, load-bearing capacity and use of key component parts of the hot water bag, minimizing the possible risks of the product, and providing guarantee for product quality and market circulation.

[0014] The structural design of the utility model can adapt to the testing of hot water bags of various shapes and sizes, and is also very easy to operate.

[0015] The technical solution of the utility model will be illustrated by way of examples in conjunction with the accompanying drawings and embodiments. Description of the Drawings
